What is Multi-Slide Die Casting??
Multi-Slide Die Casting is an advanced form of hot chamber die casting that uses four (or more) slides moving simultaneously to form highly intricate geometries in a single cycle. Unlike conventional two-slide systems, multi-slide tooling enables the production of parts with undercuts, holes, threads, and thin walls that would normally require multiple machining steps.
In this process, molten zinc or magnesium alloy is injected into a precisely engineered die, while independent slides form complex features directly within the casting cycle. This eliminates the need for secondary operations such as drilling, milling, or assembly, resulting in faster production, reduced costs, and superior dimensional accuracy (up to ±0.02 mm).
Compared with traditional hot chamber die casting, multi-slide die casting offers greater design flexibility, tighter tolerances, and shorter lead times for small-to-medium sized precision components. The process also produces excellent surface finishes, making parts ready for plating, coating, or painting without extensive post-processing.
Because of its speed, precision, and efficiency, multi-slide die casting is widely used in industries such as automotive, electronics, medical devices, telecommunications, and consumer products, where small, complex, and high-volume components are required.

How Multi-Slide Die Casting Works
Multi-Slide Die Casting (MSDC) is an advanced hot chamber die casting process designed for producing small, intricate, and high-precision components. Unlike conventional die casting, which typically uses two slides, MSDC utilizes four or more perpendicular slides that move simultaneously. This unique tooling design allows complex geometries — including undercuts, holes, threads, and thin walls — to be formed in a single cycle without secondary machining. Here is a step-by-step breakdown of how Multi-Slide Die Casting works:
Step 1. Mold Preparation and Preheating
- Clean and preheat the multi-slide die to 150–250°C.
- Reduces thermal shock and prevents cracking.
- Ensures smooth metal flow, dimensional stability, and high surface quality.
Step 2: Molten Metal Preparation
- Melt zinc or magnesium alloy in the integrated furnace.
- Maintain precise temperature to avoid oxidation.
- Guarantee consistent fluidity for accurate injection.
Step 3: Metal Injection into the Die
- Molten metal is injected under controlled pressure into the die cavity.
- Multiple slides move simultaneously to form intricate features.
- Minimizes turbulence and ensures complete filling of thin walls and undercuts.
Step 4: High-Pressure Filling & Feature Formation
- Force molten alloy into every cavity while slides form detailed features.
- Captures complex geometries with tight tolerances (up to ±0.02 mm).
- Reduces porosity and ensures excellent surface finish.
Step 5: Solidification Under Pressure
- Maintain pressure as the metal cools and solidifies.
- Prevents shrinkage, warping, and ensures consistent mechanical properties.
Step 6. Die Opening & Part Ejection
- Retract slides and open the die.
- Eject solidified part carefully to prevent damage.
- Inspect for visible defects before further processing.
Step 7. Flash Removal & Trimming
- Remove flash, runners, and gates.
- Parts reach near-net shape, minimizing secondary finishing.
Step 8. CNC Machining, Finishing & Inspection
- Machine critical surfaces if required.
- Conduct quality checks: X-ray, leak tests, CMM, and dimensional reports.
- Ensure all components meet specifications and industry standards.
